Sigma-7 Servo Drives

Choose improved efficiency for your application

The intelligent system design of our Sigma-7 series ensures high overall efficiency and performance of your machinery and equipment. Sigma-7 servo drives are easy to implement, commission and use. Sophisticated functions like vibration suppression reduce stress on machine parts and significantly improve throughput.

Seven reasons for Sigma-7

Wide power range

  • Very compact motors from 50 W to 15 kW
  • Linear motors iron core and ironless with a peak force up to 7,560 N
  • Direct drives with torques from 2 Nm up to 600 Nm

Lower production costs

  • Speed loop bandwidth of 3.1 kHz
  • Shorter settling time, reduced positioning time, higher throughput

Higher performance

  • Overload 350 % for 3 – 5 seconds
  • High peak torque, fast acceleration

Energy savings and higher productivity

  • High peak torque, fast acceleration, no amplifier oversizing
  • Lightweight mechanics

Smooth integration of mandatory legal safety standards

  • The STO function is implemented by default in all Sigma-7 series servo amplifiers
  • Build safer machines - Sigma-7 safety modules satisfy the requirements of SIL3/PLe (Cat. 3)
  • The functions SS1, SS2, SOS and SLS are standard in each safety module
  • 3 different option modules are available with up to 14 safety functions

Very low heat generation

  • Optimized magnetic circuit improves motor efficiency
  • Improved motor efficiency reduces heat generation by about 20 %
  • Ambient temperature from -5 to 55 °C (max. 60 °C with derating)

Next level 24-bit absolute encoder for maximum accuracy

  • Resolution of 16 million pulses per revolution for extremely precise positioning

Very high precision teamed up with fast, smooth operation

  • Ripple compensation for highest demands in smoothness and dynamics
  • Even for machines for which speed loop gains cannot be set high

Even more reliability for your production

  • More than 22 million servo systems in the field
  • Improved machine reliability, reduced service and maintenance costs, less downtime

Quick setup in just 3 minutes

Presets in the amplifier software simplify commissioning. A ‚tuning-less‘ function allows immediate use without the need for complex parametrisation or special knowledge of control equipment, while an auto-tuning function ensures quick adjustment.

Space saving

New book-style housing supports gapfree, side-by-side installation of amplifiers even in small spaces. This makes it possible to realize high performance density inside a cabinet. The needed space is reduced to a minimum, allowing it and the drive electronics to be integrated in the machine.

Eco friendly

Motor efficiency reduces heat generation by up to 20 %. The possible DC power coupling of axes allows energy sharing and energy savings of up to 30 %.

Cost saving

Sigma-7 reduces the overall costs by providing faster machine setup, higher throughput with more products in less time and reduced machine downtimes due to it's high reliability.

Savings through performance

With a best in class frequency response of 3.1 kHz, Sigma-7 SERVOPACKs can reduce settling time to less than 4 ms. Compared to a standard system with  40 ms settling time as an example, a pick & place unit based on Sigma-7 components can save a significant amount of money.
